Fields

columns: Vec<ColumnChunk>

👎Deprecated since 57.0.0: The format module is no longer maintained, and will be removed in 59.0.0

Metadata for each column chunk in this row group. This list must have the same order as the SchemaElement list in FileMetaData.

total_byte_size: i64

👎Deprecated since 57.0.0: The format module is no longer maintained, and will be removed in 59.0.0

Total byte size of all the uncompressed column data in this row group *

num_rows: i64

👎Deprecated since 57.0.0: The format module is no longer maintained, and will be removed in 59.0.0

Number of rows in this row group *

sorting_columns: Option<Vec<SortingColumn>>

👎Deprecated since 57.0.0: The format module is no longer maintained, and will be removed in 59.0.0

If set, specifies a sort ordering of the rows in this RowGroup. The sorting columns can be a subset of all the columns.

file_offset: Option<i64>

👎Deprecated since 57.0.0: The format module is no longer maintained, and will be removed in 59.0.0

Byte offset from beginning of file to first page (data or dictionary) in this row group *

total_compressed_size: Option<i64>

👎Deprecated since 57.0.0: The format module is no longer maintained, and will be removed in 59.0.0

Total byte size of all compressed (and potentially encrypted) column data in this row group *

ordinal: Option<i16>

👎Deprecated since 57.0.0: The format module is no longer maintained, and will be removed in 59.0.0

Row group ordinal in the file *

Trait Implementations

impl Clone for RowGroup

fn clone(&self) -> RowGroup

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for RowGroup

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Hash for RowGroup

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for RowGroup

fn cmp(&self, other: &RowGroup) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for RowGroup

fn eq(&self, other: &RowGroup) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for RowGroup

fn partial_cmp(&self, other: &RowGroup) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl TSerializable for RowGroup

fn read_from_in_protocol<T: TInputProtocol>(i_prot: &mut T) -> Result<RowGroup>

Reads the struct from the input Thrift protocol

fn write_to_out_protocol<T: TOutputProtocol>( &self, o_prot: &mut T, ) -> Result<()>

Writes the struct to the output Thrift protocol

impl Eq for RowGroup

impl StructuralPartialEq for RowGroup
